“But there were things that felt like they should be mine and felt like they should always be mine.”

Fans of the series have witnessed some pretty raw scenes during the six-part series, which focuses on four girlfriends in New York working, living and loving their way through their 20s.

And while Marnie’s character — who is both universally loved and loathed by fans around the world — has had more sex scenes than any other Girls characters, she won’t follow her co-stars lead and get naked on set.

While testing for the “Girls” pilot, Williams said she was signing her contract for the show when she was asked to sign a nudity waiver for HBO.

“I said, ‘Well, I’m not going to sign it.’ And my agents were like, ‘What?’ ‘Just tell them I’m not going to sign it,’” she said.

“And they were so stunned and so up against it time-wise, that I think they were just like, ‘All right. She’ll change her mind. She’ll get swept up in the vibe of the show. Whatever. Don’t make her sign it.’”

“Part of making sure that Marnie doesn’t feel un-intimate in that way is making sure that we see her in very intimate situations even if she isn’t showing all of herself. You are still being shown a lot of vulnerability, even though I’m not showing all of myself.

“No one guesses that I’ve had the most sex scenes of everyone on the show, everyone thinks its Lena, even though people have never seen my boobs.”

Williams said by season two, producers gave up asking if she’d appear naked.

“Maybe part of it, too, was growing up with a parent in the public eye and being aware of the fact that … I didn’t want to give my future hypothetical children another avenue by which to be made fun of,” Williams said.

“I just didn’t want to give them another thing to have to deal with — is people showing up to school with old Google images of their naked mom. It just didn’t feel like me.”
